So I am on the way with my OTS 50 build and I have a few questions. I have been reading on the forum for a few hours and cant seem to find what I need.
Is the bus bar "floating" above the pots? As in only being held by its connections to components/pots.
On the ceriatone layout there is a numbering system for all the connections like "b13, b14, f3, f5, ect". Whats the story with all of these? I feel like I am missing out on some sort of build guide haha.
Where do I use shielded leads? I am assuming on pins 2 and 7 on v1.
I have built a 5e3 and a 6m36 but the wiring of the input jacks and control pots confuse me. It seems like everything is connected. On the NOR input jack it seems like the tip is connected to ground at all times by the green wire connected to the black wire labelled A going to pin 2.
I am looking at Rob Livesey's pictures of his build and it seems like he is wiring the master, ratio, and level pots with the green connections on the layout being ground? I am confused.
Let me know if there are some better pictures to be looking at for a reference of lead dress and how to wire up the controls. Or maybe a helpful thread that covers stuff like this that I have missed.
I have appreciated reading your findings on other threads T Wilcox and SoundPerf. Thanks in advance.
Hey
1. Yes the bus bar is floating and held by the connections! it will be very secure once you have them all soldered. I actually just did mine on my HRM yesterday.
2. Not sure about numbering system but more lettering. There are 2 of each, so in other words where you see A at one point a wire will go from it to the A at another point and so on. The way to route the wire is on you or you can check pics at Ceriatone site. Edit: ok just checked layout for your OTS50 and it does have a numbering system of some sort for most every wire. Not sure what it is and would have to say it is unnecessary for the build, I built the FM model and did not need to use any such system if that helps. Probably a way for Nik to help troubleshoot over the email with someone ( check the connection at B-14 )
3.No build guide but on my first one the build video
http://www.overtonehrm.com/ helped out quite a bit.
4. If you look at the layout where the wires land at the level, ratio and master pots you will notice there is a little circle where the wire splits off. that is the shield and anywhere you see that it is to be a shielded cable. Take wire x for example, at the other end where it meets the board the shield is cut off. The shield is only grounded at one end! Not at pins 2 and 7 but where they meet the terminal strip the wire labeled A and B would be the ungrounded side of the shielded cables.
5. The cliff jacks are such that when jack is inserted the ground is lifted. They are called shorting jacks but they actually open the circuit when jack is inserted. The layout is correct. Make sure you wire exactly as pictured. Check the pics on the ceriatone website as well, they are very helpful for doing this build.
6. Not sure about Rob's build where are you looking at this? Not looking at your layout I beleive the green connections you speak of are the shields which will be grounded and the center lead of coax's goes to othere terminals on pots.
7. I had trouble understanding how to lead dress the RG-174 on my first build, there is a thread from me asking about it. Do a search here ( RG-174 ) it should pop up and if I recall there was very good advice on it.
Watch that video I linked and then check pics at Ceriatone site and if you have further questions feel free to ask
Let me know if anything here doesn't make sense and I will try to explain further
One last thing, before reposting in this thread, start a new thread labeled need help with new OTS50 build. This will help future builders, atleast if Nik ever brings back the kits
